1 Cronicles 18:4
And David took from him a thousand chariots, and seven thousand horsemen, and twenty thousand footmen: David also houghed all the chariot horses, but reserved of them an hundred chariots.
Huh?
You did not even address the numbers in question (seven thousand and seven hundred).
Please tell me that this is a mistype.
You forgot the address the point, which is at what age did he begin his reign, eight or eighteen?
That makes sense.
Of course, I have not actually looked at the verses in context yet either.
Interesting as this is, what does it have to do with anything?
Please present the verse(s) that support this theory.
I tend to agree with this explanation.
First one looks like you mixed a few things up and will needs to fix it.
At least I hope that is what happened.
Otherwise the first response is nothing but irrelevant rambling.
I will concede that the second one is a possible plausible explanation.
The third one did not address the point at all.
As it stands, it appears that the fourth one may be a reasonable explanation, but I will first needs to research the context.
The fifth one seriously looks like you took the easy way out.
However more research on context will be needed before I can confirm or discount it.
I tend to agree with the sixth explanation, based upon my current understanding of the story.
